Daily Inhalation Rate and Time‐Activity/Location Pattern in Japanese Preschool Children

Lack of data on daily inhalation rate and activity of children has been an issue in health risk assessment of air pollutants. This study aimed to obtain the daily inhalation rate and intensity and frequency of physical activity in relation to the environment in Japanese preschool children. Children aged four–six years (n= 138) in the suburbs of Tokyo participated in this study, which involved three days' continuous monitoring of physical activity using a tri‐axial accelerometer and parent's completion of a time/location diary during daily life. The estimated three‐day mean daily inhalation rate (body temperature, pressure, saturated with water vapor) was 9.9 ± 1.6 m³/day (0.52 ± 0.09 m³/kg/day). The current daily inhalation rate value of 0.580 m³/kg/day proposed for use in health risk assessment in Japan is confirmed to be valid to calculate central value of inhaled dose of air pollutants in five‐ to six‐year‐old children. However, the 95th percentile daily inhalation rate of 0.83 m³/kg/day based on measurement for five‐year‐old children is recommended to be used to provide an upper bound estimate of exposure that ensure the protection of all five‐ to six‐year‐old children from the health risk of air pollutants. Children spent the majority of their time in sedentary and light level of physical activity (LPA) when indoors, while 85% of their time when outdoors was spent in LPA and moderate‐to‐vigorous physical activity. The results suggest the need to consider variability of minute respiratory ventilation rate according to the environment for more refined short‐term health risk assessment.     

隋唐道教术数学派与传统数学关系考论

关于隋唐时期道教在传统数学领域作出的贡献,学术界已有较多的探讨,然仍显不足。要言之,隋唐道教术数学派坚信术数与数学互为表里,通过"算"、"数"之共性将术数、数学融为一体,并以兼摄数学之术数求道证道。这些思想使得其自身在传统数学(包括天文历算)的理论和实践上作出了一定的贡献,也影响了传统数学的精神气质和发展趋势。而道教术数学派在术数、数学上的研究,对道教自身的发展也有着重要的意义。     

Testing the Vision: Preschool Settings as Places for Meeting,Bonding and Bridging

The OECD (2006 Starting Strong II: Early Childhood Education and Care. OECD Publishing: Paris) envisions early childhood education and care settings as meeting places for diverse social groups; places that build social capital. This vision was assessed in a comparison of three preschools types: full‐fee paying, subsidised‐fee and publicly funded. The social composition within each was examined and the connectedness of the children (n = 472) who attended compared. Publicly funded preschools had more socially diverse populations. The quantity of social connectedness did not differ but children in publicly funded preschools described higher quality social relationships. Not all preschool settings are socially diverse but, where they are, the quality of relationships is highest.     

数学基础课教学中问题意识的培养策略——以解析几何教学为例

探讨了数学基础课教学中培养问题意识的策略:强化基础,在清晰的知识储备中孕育问题;研究性教学,在教学过程中突出问题;注重应用,在实践中激发问题;大胆质疑,在求新求异中发现问题;营造环境,寓方法引导于教学过程之中。     

透析生活史研究在古德森教师研究中的角色

生活史研究已日渐运用于当代教育研究中。英国教育社会学家艾沃·古德森不仅较早地将其用于课程研究，还更多地用于教师研究。文章考察了古德森不同阶段的教师研究，分析了生活史研究在教师研究中所扮演的角色：为教师生活研究提供研究方法；为在"中间地带"建构理论提供资源；为促成教师"叙事学习"和"叙事教学"场域奠定基础。指出运用生活史研究是古德森教师研究生涯中一以贯之的思想，背后有其对教师深刻的社会关怀。这一思想在其教师研究中扮演着多重角色，对我国教师和教师教育研究者及实践者而言，有诸多借鉴意义。     

学前教育师范生TPACK现状调查及教学改革建议

在“互联网+”及多元文化知识不断融合的教育背景下，信息技术在教学中被提升到一个新的高度。为了解学前教育师范生群体对信息技术知识在教学活动中的应用程度，笔者采用自编的《学前教育师范生TPACK》量表对220名在校学前教育师范生进行调查。统计分析发现：1）学前教育师范生的总体TPACK知识掌握较好，但技术知识仍然较为薄弱；2）学前教育师范生TPACK知识存在显著的年级差异，但性别差异不显著；3）信息技术爱好和训练会造成学前教育师范生TPACK知识的差异。应采取的对策：1）注重培养学前教育师范生的信息技术知识和能力；2）大力推进第二课堂，促进TPK和TCK的发展；3）进行产学研合作，提升学前教育师范生的TPACK水平。     

Children’s narrative story stem responses: Contributions of executive functioning and language proficiency to relationship representations

Story stem narrative tasks provide insight into young children's inner experiences. Little research has investigated how developmental capacities impact narrative content and process. This study evaluates the influence of executive functioning (EF) and language ability on children's narratives. Data were gathered from 210 low‐income children. EF and language ability were assessed at age 4 and EF was assessed at age 6 via direct examination, cognitive‐motor tasks, and examiner ratings. Children's responses to eight story stems were gathered at age 6; three latent narrative variables were constructed (Prosocial, Aggressive/Conflict, and Avoidance/Danger), and Narrative Coherence was rated. Results of longitudinal path analyses in structural equation modeling demonstrated age 4 EF significantly predicted all narrative outcomes. Language ability independently predicted Prosocial and Narrative Coherence, and had an influence on Aggression/Conflict when modeled with EF. Age 6 EF mediated the relationship between age 4 EF and narrative outcomes. Findings provide insight into developmental abilities that influence on children's narrative responses to challenging interpersonal scenarios. Future research should study parent–child relations, EF, and language abilities simultaneously.     

Participant roles in preschool bullying: The impact of emotion regulation,social preference,and quality of the teacher–child relationship

The present work investigated whether emotion regulation and social preference were associated with participant roles in bullying as a function of the quality of the relationship with teachers. Participants were 332 children (172 boys), in the age of 42–76 months (M = 58.74; SD = 7.84). Peer nominations were employed to assess social preference and participant roles (bullying, victimization, defending the victim, and outsider behavior). Teachers completed the Emotion Regulation Checklist, which yields the dimensions of emotion regulation and lability/negativity, and the Student – Teacher Relationships Scale, to evaluate conflict and closeness with the teacher. Multilevel models highlighted that emotional lability was positively associated with bullying and outsider behavior, emotion regulation was positively related to bullying and defending behavior, and social preference was negatively associated with bullying and victimization and positively with defending behavior. Interactions indicated that lability and low social preference were associated with bullying, and emotion regulation with outsider behavior, in children with a conflictual relationship with the teacher whereas social preference was related to defending behavior in children with a close relationship with the teacher. Results are discussed highlighting the importance of the quality of teacher–child relationship and the relevance of intervention programs aimed at promoting social wellbeing in preschool.

Desire for the desert: racialising white teachers’ motives for working in remote schools in the Australian desert

Abstract

Distinct from rurality, the Australian desert has long functioned as a signifier of remoteness in the dominant imagination; a product of spatialised binary relations between ‘progressive’ (white) mainstream or idealised white countryside, and disordered/dangerous Aboriginal periphery. Remoteness constitutes a complex racial dynamic that has historically mediated white teachers’ and missionaries’ desires to travel to the social margins. This article adopts a discursive understanding of remoteness to examine contemporary white teachers’ decisions to work in Aboriginal schools in the desert – decisions that are often articulated through unwitting recourse to the ‘three Ms’ or ‘tourist’. The article explores these identity constructs and how they enable different performances of whiteness. It examines how white people’s desires are often covertly raced but does not however, position the teacher as a priori racist. Rather, desire is theorised as a social construct in which subjects invest, which may at times contribute toward processes of decolonisation. This rendering moves beyond a logic of individualism and underpins the argument that recognising how these dynamics play out is vital with respect to understanding the place of white teachers inside remote Indigenous Education. Moreover, such insights are valuable for appreciating how whiteness continues to be reproduced in White Australia under a guise of good intentions.
